As a highly integrated and high-performance core component, the system on chip (SoC) receiver chip relies heavily on its internal clock source for its performance. In the Beidou navigation equipment, the core component is the satellite navigation receiving SOC chip, which integrates RF, CPU, baseband processing, RTC and other functions internally. The implementation of RTC function requires a 32.768KHz external reference clock. For the application of receiving SOC chip reference clock in Beidou navigation equipment, we recommend Epson Crystal Company's 32.768K crystal oscillator series, FC-12M part number X1A000061000200 crystal resonator. Due to its small size and low power consumption, FC-12M passive crystal oscillator has three commonly used load capacitors to choose from: 12.5PF, 7PF, and 6pF. Among them, FC-12M 32.768kHz 12.5pF (X1A000061000200) and FC-12M 32.768000 32.768kHz 7pF are the standard models recommended by Epson.

The implementation of the RTC function of the Beidou navigation receiving SOC chip requires an external reference clock. The X1A000061000200 chip oscillator can provide a standard 32.768KHz clock, which can ensure accurate internal timing of the navigation chip in applications with weak navigation signals. The navigation receiving chip is generally used in handheld, car mounted and other navigation devices, with strict volume requirements. The X1A000061000200 chip oscillator adopts a 2.0 * 1.2 * 0.6mm chip package, which is small, mature and stable, and easy to mass produce. The FC-12M crystal oscillator load capacitor is the mainstream 12.5pF, and conventional capacitors can be used to achieve load capacitor matching of passive crystals.

The application advantages of FC-12M in SOC receiving chips:

1. Improve data transmission speed: High precision synchronization: FC-12M provides high-precision clock signals to ensure synchronous data transmission operations of SoC receiving chips, improving overall transmission speed. Reduce latency: The highly stable crystal oscillator signal supports SoC receiving chips to reduce latency in data transmission and enhance user experience.

2. Improve reliability: The high reliability design of FC-12M ensures the stability of the SoC receiving chip during long-term use, reducing the risk of system failure. Wide temperature adaptability: Maintain high performance within a wide temperature range, ensuring stable operation of SoC receiving chips in various environments.

3. Design flexibility; Compact packaging: The compact size design makes it easy to integrate into various SoC receiver chips, whether they are consumer grade products or industrial grade solutions. Diversified interface support: Compatible with multiple interface and controller designs, suitable for different types of SoC receiver chip solutions.
